The loss of market value is determined as follows:
if the amount of itemized coverage for the article is less than the market value immediately before the loss, we will apply the percentage change to the market value immediately before the loss.
If the amount of itemized coverage for the article is equal to or greater than the market value immediately before the loss, we will apply the percentage change to the amount of itemized coverage for that article.
“Percentage change” means the change in market value resulting from the covered loss, after restoration if any, expressed as a percentage.
